n-category = (n,n)-category
n-groupoid = (n,0)-category
An (∞,n)-category $\mathcal{C}$ is said to have 1-adjoints if in its homotopy 2-category $Ho_2(\mathcal{C})$ every 1-morphism is part of an adjunction. By recursion, for $n \geq 3$ and $k \geq 2$ an (∞,n)-category has $k$-adjoints if for every pair $X, Y$ of objects the hom (∞,n-1)-category $\mathcal{C}(X,Y)$ has adjoints for $(k-1)$-morphisms.
An $(\infty,n)$-category has all adjoints (or just has adjoints, for short) if it has adjoints for $k$-morphisms for $0 \lt k \lt n$.
The notion appears first in section 2.3 of
A model for $(\infty,n)$-categories with all adjoints in terms of (∞,1)-sheaves on a site of a variant of $n$-dimensional manifolds with embeddings between them is discussed in

Abstract Chiral/factorization homology gives a procedure for constructing a topological field theory from the data of an En-algebra. I’ll explain a multi-object version of this construction which produces a topological field theory from the data of an $n$-category with adjoints. This construction is a consequence of a more primitive result which asserts an equivalence between n-categories with adjoints and “transversality sheaves” on framed $n$-manifolds - of which there is an abundance of examples.
